DOOR-LATCHING IIIEANS.

Application led November To all tolto/nt t may cmwcwt.'

Be it known that I, ADoLPH KAssLnR, residing at 1544 Bryant Avenue, NewYork, N. Y., and being a citizen of the United States, have inventedcertain new and useful Improvements in a Door-Latching Means, of whichthe following is a full, clear, and exact description, such as willenable others skilled in the art to which it appertains to make and touse the same, reference being' had to the accompanying drawings whichillustrate the preferred form of the invention, though it is to beunderstood that the invention is not limited to the ex- 3 act details ofconstruction shown and described, as it is obvious that variousmodifications thereof within the scope of the claims will occur topersons skilled in the art.

In said drawings:

Fig. 1 is a fragmentary view in elevation of a car with the inventionapplied thereto;

Fig. 2 is a view on a larger scale with part in section of one of thelatching mechanisms shown in Fig. 1 the latch being shown in engagementwith the door;

Fig. 3 is a section taken on line 3-3 of Fig. 2;

Fig. 4 is a view similar to Fig. 2 the latch being shown (ilisengagedfrom the door;

Fig. 5 is a View similar to Fig. 2 of a modified form of the inventionand Fig. 6 is a section taken on line GwG of F ig. 5.

It is an object of this'invention to provide a latching means for cardoors which shall be simple and economical in construction. comprisingfew easily replaceable parts, which shall be readily operable to engageand disengage the door and which may be locked in engaging position.

In the drawings the invention is shown applied to the side sheet 1 of acar between the side posts 2 and engaged with the angles 8 which aresecured to the car door and which project slightly beyond the car sideso as to be engaged by oppositely disposed latches. Each latch mechanismcomprises a base plate 4 provided with a plurality of cylindricalprojections 5 and G and secured to the car side by the rivets 7, 8 and9, the rivets 7 and 8 passing through openings in the projections 6 and5 respectively. Pivotally mounted on the projection 5 and securedthereon by a washer 10 and rivet 8 is a latch or hook 11 provided.

with a flat surface or seat 12 which is adapted to engage beneath theflange 123 of the angle 3. Pivotally mounted on the projection 6 andsecured thereon by ay washer 14 and rivet 7 is an operating handle orarm 15 which is provided with a projecting lug 1G having a plurality ofangular disposed surfaces 17 and 18, each surface being inclined to theaxis of the arm 15, which are adapted to engage corresponding surfaces19 and 20 formed on the latch 11 when the handle 15 and latch 11 arefully engaged as shown in Fig. 2. In this position it will be noted thatthe handle 15 is in engagement with a stop 26 formed integral with thebase plate 4.

`With the seat 1Q in engagement with the flange 13. as shown in Fig. 2,the handle 15 must be rotated about its pivot 7 disengaging the lug 16from the latch 11 in order that the hook may be disengaged from beneaththe angle 3 to permit the door to be dropped. With the projection 16disengaged from the latch 11, as shown in Fig. 4, the hook 11 willassume a vertical position when the door is opened. As the door isbrought to the closed position,y the inclined surface 21 of the latch 11will be engaged by the flange 13 of the angle 3 and the Vlatch moved toone side. then the flange 123 passes beyond the inclined surface 21 thelatch will fall in back of the flange 13, assuming a position such as isshownrin dotted lines in Fig. 4. The handle 15 is then operated bringingthe surface 1S of the projection 1G into engagement with the surfaces 19and 2O on the latch 11. Pressure is then exerted upon the handle 15 andthrough the engagement of the projection 16 with the surfaces 19 and 2Oon the latch 11, causes the latch to be forced in under the flange 13until the projection 16 `is moved to the position shown in Fig. 2,raising the door to the fully closed position. The relation of thesurfaces 17, 18 and 19, 20 is such that the pressure exerted upon theprojection 16 by the latch 11 cannot cause the projection 16 to becomedisengaged from the latch 11.

In the modification of the invention shown in Figs. 5 andf) the latch111 is pivotally supported from the base plate 4 as in the othermodification. The handle 115 is' also pivotally supported from the baseplate 4. The pivot point, however, in this modification is adjacent thestop 26 and the projection 116 mounted on the handle 115 engages theside of the latch 111 away from the pivot point. In the firstmodification pressure exerted upon the handle by the latch 11 Will putthe handle under compression while in the modification shown in Figs. 5and 6 pressure exerted upon the handle 115 by the latch 111 Will causethe handle to be under tension. The projection 11G .is inclined slightlyto the axis of the handle 115 and cooperates with the inclined surfaceof the latch 111 so that when the latch is brought into engagement withthe flange of the angle 8 upon the closing of the door7 operation of.the handle 115 Vwill bring the projection 116 into contact with thesurface 120 and ivill cause the surface 112 to be forced in under theflange 13 of the angle 3 bringing the door to a fully closed position. l

What is claimed is:

1. In a car, a door, a latch for said door pivotally mounted on saidlcarand having angularly disposed contact surfaces, an operating handle, alug on said handle havingangularly disposed contact surfaces and a stopfor said handle adapted to position said lug with the contact surfacesof the lug in engagement With the Contact surfaces on the latch.

2. In a car, a door, a latch having a door engaging surface pivotallymounted on said car and an operating handle having-a Wedge shaped lugthereon adapted to engage said latch, said latch being moved to fullyclosed position by engagement with one of the surfaces of said lug andhaving angularly disposed contact surfaces engaged by said lug when saidlatch is in the fully closed position. i

8. In a car, a door, a base plate having lugs secured to said car, alatch for said door pivotally mounted on one of said lugs, an operatinghandle having a lug thereon adapted to engage said latch pivotallymounted on another of said lugs and a stop for said handle mounted onsaid base plate.

4. In a car, a door, a base plate having lugs secured to said car, alatch having an engaging surface for said door pivotally mounted on oneof said lugs, and an operating handle having' a lug thereon pivotallymounted on another of said lugs, said lug engaging said latchintermediate the pivot and door engaging surface on saidlatch.

5. In a rar, a door, a base plate having lugs secured to said car, alatch for said door pivotally mounted on one of said lugs, an operatinghandle pivotally mounted on another of said lugs and a locking camcarried by said operating handle adapted to engage said latch.

6. In a car, a door, a base plate having lugs secured to said car, adoor engaging latch pivotally mounted on one of said lugs,

an operating handle pivotally mounted on another of said lugs, a lockingcam mounted on said operating handle and engaging said latchintevizmediatethe pivot and dooi1 engaging surface on the latch and astop for said handle carried by said base plate.

7. In a car, a door, a base plate having lugs secured to said car, alatch for said door pivotally mounted on one of said lugs and havingangularly disposed contact surfaces7 an operating handle pivotallymounted on another of said lugs, a lug upon said handle having angularlydisposed contact surfaces and a stop on said base plate adapted toposition the lug on said handle with the contact surfaces on the lug inengage-W ment With the contact surfaces on the latch.'

In Witness whereof I have hereunto lset my hand in the presence of twoWitnesses.
